PFND3D10DDI_DESTROYSAMPLER callback function (d3d10umddi.h)
The DestroySampler function destroys the specified sampler object. The sampler object can be destroyed only if it is not currently bound to a display device.
Syntax
PFND3D10DDI_DESTROYSAMPLER Pfnd3d10ddiDestroysampler;
void Pfnd3d10ddiDestroysampler(
D3D10DDI_HDEVICE unnamedParam1,
D3D10DDI_HSAMPLER unnamedParam2
)
{...}
Parameters
unnamedParam1
hDevice [in]
A handle to the display device (graphics context).
unnamedParam2
hSampler [in]
A handle to the driver's private data for the sampler object to destroy. The Microsoft Direct3D runtime will free the memory region that it previously allocated for the object. Therefore, the driver can no longer access this memory region.
Return value
None
Remarks
The driver can use the pfnSetErrorCb callback function to set an error code.
The driver should not encounter any error, except for D3DDDIERR_DEVICEREMOVED. Therefore, if the driver passes any error, except for D3DDDIERR_DEVICEREMOVED, in a call to the pfnSetErrorCb function, the Direct3D runtime will determine that the error is critical. Even if the device was removed, the driver is not required to return D3DDDIERR_DEVICEREMOVED; however, if device removal interfered with the operation of DestroySampler (which typically should not happen), the driver can return D3DDDIERR_DEVICEREMOVED.
